C++ use SSE instructions for comparing huge vectors of ints

http://stackoverflow.com/questions/17791892/c-use-sse-instructions-for-comparing-huge-vectors-of-ints

double RAND_MAX 1.0 n Returns a timestamp 'now' in seconds incl. a fractional part . inline double timestamp struct timeval.. 20 faster than the original scalar code on a Core i7 #include smmintrin.h int getDiff_SSE int indx1 int indx2 int result..

format of for loops

for int i 0 i 5 i movl 0 12 ebp jmp L2 L3 leal 12 ebp eax incl eax L2 cmpl 4 12 ebp jle L3 for int i 0 i 5 i movl 0 12 ebp.. for int i 0 i 5 i movl 0 12 ebp jmp L7 L8 leal 12 ebp eax incl eax L7 cmpl 5 12 ebp jne L8 I think jle and jne should translate..

Hoisting the dynamic type out of a loop (a.k.a. doing Java the C++ way)

address is in memory pointed at by rax 61 addl eax r14d 62 incl ebx 63 cmpl r13d ebx 64 jne L9 If I remove the virtual descriptors.. 78 call __ZNK1A1fEv Call the F method. 79 addl eax r13d 80 incl ebx 81 cmpl r12d ebx 82 jne L16 So the difference in the above.. up each time through the loop. Source that was compiled #include iostream struct A virtual int f const return 0 struct B A..

What does the “lock” instruction mean in x86 assembly?

http://stackoverflow.com/questions/8891067/what-does-the-lock-instruction-mean-in-x86-assembly

in Qt's source q_atomic_increment movl 4 esp ecx lock incl ecx mov 0 eax setne al ret .align 4 0x90 .type q_atomic_increment.. on memory INC XCHG CMPXCHG etc. in this case it is the incl ecx instruction which inc rements the l ong word at the address.. off the stack into the ecx register then it does lock incl ecx to atomically increment that variable by 1. The next two..
